ZL-37 is a highly sensitive Type 1 penetrant crucial for detecting fine defects in critical components like titanium turbine parts and high-stress investment castings. Its non-water-soluble nature minimizes the risk of washing away from shallow defects, ensuring the most reliable penetrant testing method. With a high flash point, it offers extended tank life in dip tank applications and can also be applied via electrostatic spray.
Removal options include ZE-4E Method B for lipophilic emulsification or ZR-10E Method D for hydrophilic emulsification.
ZL-37 is qualified under QPL SAE AMS 2644 and approved by Pratt & Whitney for use.
Improve indication detection in the most critical applications
- Creates the clearest, brightest indications for even the finest flaws due to very strong UV and thermal stability
- Highest fluorescent brightness of any Level 4 penetrant for high-contrast indications that are easy for inspectors to see – even when the indications are very small
- Indications stand out more since background fluorescence is minimized; emulsifiers only remove surface penetrant without the risk of over-washing
Maximize penetrant inspection process control
- Prevents over-washing since ZL-37 cannot be removed with water (unless combined with an emulsifier)
- Post Emulsifiable penetrant system is less susceptible to human error since only surface penetrant is removed in the final rinse stage
Wide range of inspections
- Inspect a wide range of high-value components without fear of corrosion or specification non-conformance
- Meets all major industry and NDT specification requirements, including Aerospace Prime and OEM specs, AMS 2644 and ISO 3452
